NES Challenge - Donkey Kong Jr Math in 1:12:04 [190/714]
Actually a great education game. I would recommend for parents, but the controls can screw you up as there is no back button I can find. A few times I made a directional input by mistake but couldn't fix the error. While that is on me, it isn't on my calculation.
So the game has good graphics and sound, on par for 1983, this was clearly a game to move consoles into homes in hopes of kids learning math - it is the only edutainment game on the system. That said, I would have worked harder at math if my parents had gotten me this game and took the others away as punishment. :)
Frankly I cannot recommend this for someone to purchase unless they are looking to complete a collection and would rank this in the middle of the library. It's not a bad game and it is a bit addictive, however at the end of the day you are doing basic math. It might be good to go back to once in awhile just to brush up and not advertise your math skills while exhausted at the end of the day for the internet to judge you. =D
